GEORGE A. HUMPHREY, OF NEW YORK, N. Y.

SELF-HEATING SAD-IRON.

T 0 all whom it may concern:

Be it known that I, GEORGE A. HUM- rrinnv, a citizen of the United States, residing at the city of New York, N. Y., have in vented certain new and useful Improvements in Self-Heating Sad-Irons, of which the following is a specification.

This invention relates to improvements in selfrheating sad irons.

The main objects of this invention are: First, to provide an improved self-heating sad iron which is very eilicienu that is, one which may be quickly heated to any desired temperature and maintains a substantially oven temperature, and one which is economical in fuel consumption. Second, to provide an improved self-heating sad iron in which the heat is effectively delivered to the bottom of the iron and the bottom of the iron is evenly heated. Third, to provide an improved self-heating sad iron which may be very easily and conveniently manipulated.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a perspective view of a structure embodying the features of my invention. Fig. II is a vertical longitudinal section on a line corresponding to line 2-2 of Fig. III. Fig. III is a horizontal section on a line corresponding to line 3-3 of Fig. II. Fig. IV is a detail transverse vertical section on a line corresponding to line 4l4 of Fig. III. Fig. V is an inverted perspective view of the burner body with the burner thereon. Fig. VI is an enlarged detail view partially in section, on a line corresponding to the broken line 6-6 of Fig. II.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the body 1 of my improved sad-iron is a chambered casting. The inner side of the bottom is provided with an outerchannel 2 adjacent the Specification of Letters Patent.

Serial No. vsassa walls and an inner longitudinal channel 3. Between the outer and inner channels is a series of pockets or recesses I, 5, 6, 7 and 8. There is a single recess 4. arranged at the front end of the iron, the recesses 5, 6, 7 and 8 being arranged in opposed pairs. See Fig. III.

The walls of the front recess l and of the front pair of recesses 5 are higher on their inner sides,that is, adjacent the inner channel 3, so that in effect, these recesses open into the outer channel 2. The outer walls of the recesses or pockets 6 are higher than the inner walls, so that these recesses in effect open into the central or inner channel 3. The side walls of the recesses 7 and 8 are of substantially the same height so that these recesses open into both the inner and outer channels. The walls are provided with air openings 11 which open into the outer channel, the lower edges of the openings being substantially flush with the bottom of the channel.

The top 12 is chambered to receive the burner body 13. The upper edges of the walls of the body are notched at 14. to provide elongated air openings between the top and the body. The top is secured upon the body by means of the screws 15. The burner body 13 is tubular and is secured in the top by the screw 16.

The tubular burners 17 are arranged on the body to project downwardly therefrom and are directed toward the pockets or recesses, their lower ends being quite close to the bottom so that the jets issuing therefrom strike or impinge in the recesses.

The mixing tube 18 is arranged through the rear wall of the top to project into the burner body, as clearly shown in Fig. II, and is adjustably retained by the set screw 19. The handle 20 is secured to the top by means of the screws 21, the screws being arranged through spacing members 22, the deflector plate 23 above the spacing members and the spacing or insulating members 24: above the plate. This provides an effective heat insulating connection for the handle to the top.

The nozzle 25 is carried by the depending bracket arm 26 secured to the rear end of the handle. The nozzle is provided with a regulating needle valve 27, and with a con trol valve 28 having a port 29 t-herethrough, and an annular passage-like port 30 which registers at all times with the gas passage Ill) 31 of the hose nipple 32. The gas can be cut down to a minimum when the user desires to leave the iron temporarily. The valve is provided with a lever-like finger piece 33 having a laterally-turned end 3%. The mixing tube 18 serves as a stop for this finger piece in one position, and the arm of the bracket for the other position. The nozzle is thus supported in operative relation to the mixing tube, but being supported by the handle, which is effectively insulated, the

heat is not transmitted to the nozzle and through it to the gas hose or tube.

t will be understood that these irons are to be used with a flexible hose or conduit, and one serious objection has heretofore been that the heat transmitted to the hose would soon destroy the sam or interfere with the effective delivery of the gas. By arranging the parts in this manner, the gas is delivered to the mixing tube in a comparatively cool condition, and the delivery tube is protected from the heat so that it is not injured or destroyed thereby.

The arrangement of the burners is substantially that shown in my application for patent filed June 6, 1912, Ser. No. 701,741. My present structure, however, is an improvement upon the structure there illustrated, in certain particulars.

The heat is efiectively delivered to the bottom of the iron, and further, all of the burners are supplied with the necessary air at the point of combustion so that perfect combustion results, not only in utilizing all of the fuel delivered, but delivering the heat in a very efiective manner.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
